차량의 액티브 에어 플랩 제어 시스템 및 방법{SYSTEM FOR CONTROLLING ACTIVE AIR FLAP IN VEHICLE AND METHOD THEREOF}Vehicle active air flap control system and method {SYSTEM FOR CONTROLLING ACTIVE AIR FLAP IN VEHICLE AND METHOD THEREOF}

본 발명은 차량의 액티브 에어 플랩 제어 시스템 및 방법에 관한 것으로, 더 상세하게는 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 한 차량의 액티브 에어 플랩 제어 시스템 및 방법에 관한 것이다.
The present invention relates to a system and method for controlling an active air flap of a vehicle, and more particularly, to an active air flap control system and method for allowing a flap to be opened and closed within an upper limit of a motor torque considering a vehicle speed and wind speed / wind direction. It is about.

일반적으로 플랩 제어 시스템은 차량의 라디에이터 그릴과 라디에이터 사이에 개폐가 가능한 플랩을 장착하여 제어하는 시스템이다.In general, the flap control system is a system for mounting and controlling a flap that can be opened and closed between the radiator grille and the radiator of the vehicle.

이러한 플랩 제어 시스템은 차량의 고속 주행시 플랩을 폐쇄함으로써 차량의 공기 저항을 감소시켜 주행 안정성 향상을 도모한다.This flap control system reduces the air resistance of the vehicle by closing the flap during high-speed driving of the vehicle, thereby improving driving stability.

또한, 엔진 룸 내부의 온도가 상승하여 부품이 과열될 우려가 있을 경우에는 플랩을 개방하여 엔진 룸 내부 온도를 낮추는 기능을 수행한다. 이를 위해서는 차속 뿐만 아니라, 냉각수온도, 모터 온도, 오일 온도 등 차량의 상태에 대한 신호를 받아 플랩을 개폐한다.In addition, when the temperature inside the engine room increases and there is a risk of overheating of the parts, the flap is opened to lower the temperature inside the engine room. To do this, the flap is opened and closed by receiving a signal about the vehicle's condition, such as the vehicle speed, the coolant temperature, the motor temperature, and the oil temperature.

상기한 기술구성은 본 발명의 이해를 돕기 위한 배경기술로서, 본 발명이 속하는 기술분야에서 널리 알려진 종래기술을 의미하는 것은 아니다.
The above technical configuration is a background art for helping understanding of the present invention, and does not mean a conventional technology well known in the art.

종래의 플랩 제어는 액츄에이터를 구동하는 모터 토크를 기준으로 차속의 상한값을 두고 제어를 하고 있다.Conventional flap control is based on the motor torque for driving the actuator at the upper limit of the vehicle speed.

이는 풍향과 풍속을 고려하지 않고 차속의 상한값만으로 플랩을 제어함으로써 차량의 방향과 반대의 맞바람이 불때는 예측불허의 상황으로 인해 플랩이 열리지 않고 구속되는 현상이 발생할 수 있다.This is because the flap is controlled only by the upper limit of the vehicle speed without considering the wind direction and the wind speed, and thus the flap may not be opened due to an unpredictable situation when the wind is opposite to the direction of the vehicle.

따라서, 본 발명은 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 한 차량의 액티브 에어 플랩 제어 시스템 및 방법을 제공하는데 그 목적이 있다.
Accordingly, an object of the present invention is to provide an active air flap control system and method for a vehicle that can open and close the flap within an upper limit of a motor torque in consideration of the speed and wind speed / wind direction of the vehicle.

본 발명에서, 상기 제어부는 상기 풍향과 풍속에 따른 차속 보정값을 연산하고, 상기 차량의 속도에 상기 차속 보정값을 반영한 보정속도에 따라 플랩 개폐를 제어하는 것을 특징으로 한다.In the present invention, the control unit calculates the vehicle speed correction value according to the wind direction and the wind speed, characterized in that for controlling the flap opening and closing according to the correction speed reflecting the vehicle speed correction value in the speed of the vehicle.

그리고, 본 발명에 의한 차량의 액티브 에어 플랩 제어 방법은, 풍향과 풍속에 따른 차속 보정값을 연산하는 단계; 차량의 속도에 상기 차속 보정값을 반영한 보정속도가 제1기준속도 이하와 제2기준속도 초과 사이의 범위에 있으면 플랩을 오픈 구동하는 단계; 상기 보정속도가 상기 제2기준속도 이하와 제3기준속도 초과 사이의 범위에 있으면 상기 플랩을 온도에 따라 제어하는 단계; 및 상기 보정속도가 상기 제3기준속도 이하이면 상기 플랩을 클로즈 구동하는 단계를 포함하는 것을 특징으로 한다.In addition, the active air flap control method of the vehicle according to the present invention includes the steps of calculating a vehicle speed correction value according to the wind direction and wind speed; Opening the flap when the speed of the vehicle reflecting the vehicle speed correction value is within a range between the first reference speed and the second reference speed; Controlling the flap according to temperature if the correction speed is within a range between the second reference speed and below and a third reference speed; And closing the flap when the correction speed is less than or equal to the third reference speed.

본 발명에서, 상기 보정속도가 상기 제1기준속도를 초과하면 경고등을 온 표시하는 것을 특징으로 한다.
In the present invention, if the correction speed exceeds the first reference speed is characterized in that the warning light on.

상술한 바와 같이, 본 발명은 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 함으로써 고풍속/맞바람의 경우 플랩이 오픈되지 않는 치명적인 오류를 방지할 수 있다.

이하, 실시예를 통하여 본 발명을 더욱 상세히 설명하기로 한다. 이들 실시예는 단지 본 발명을 예시하기 위한 것이며, 본 발명의 권리 보호 범위가 이들 실시예에 의해 제한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

이 과정에서 도면에 도시된 선들의 두께나 구성요소의 크기 등은 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있다. 또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다. 그러므로, 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

도 1은 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 시스템의 구성을 설명하기 위한 블럭도이다.1 is a block diagram illustrating a configuration of an active air flap control system of a vehicle according to an exemplary embodiment of the present invention.

도 1을 참고하면, 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 시스템은 차속 감지부(1)와, 풍향/풍속 감지부(2)와, 온도 감지부(3)와, 제어부(4)와, 플랩 구동부(5)를 포함한다.Referring to FIG. 1, an active air flap control system of a vehicle according to an exemplary embodiment of the present invention may include a vehicle speed detector 1, a wind direction / wind speed detector 2, a temperature detector 3, and a controller ( 4) and the flap drive part 5 are included.

차속 감지부(1)는 차량의 속도를 감지한다.The vehicle speed detector 1 detects the speed of the vehicle.

풍향/풍속 감지부(2)는 차량 주행시 풍향과 풍속을 감지한다.The wind direction / wind speed detector 2 detects the wind direction and the wind speed when the vehicle is driven.

온도 감지부(3)는 차량 내부의 냉각수와 오일과 모터 등의 온도를 감지한다.The temperature detector 3 detects the temperature of the coolant and the oil and the motor in the vehicle.

제어부(4)는 차량의 속도와 풍향과 풍속에 따라 플랩 개폐를 제어한다. 이러한 제어부(4)는 풍향과 풍속에 따른 차속 보정값(VS_CompenWV)을 연산하고, 차량의 속도에 차속 보정값(VS_CompenWV)을 반영한 보정속도(차속+VS_CompenWV)에 따라 플랩 개폐를 제어한다.The controller 4 controls the flap opening and closing according to the speed, wind direction, and wind speed of the vehicle. The controller 4 calculates the vehicle speed correction value VS_CompenWV according to the wind direction and the wind speed, and controls the flap opening and closing according to the correction speed (vehicle speed + VS_CompenWV) reflecting the vehicle speed correction value VS_CompenWV.

플랩 구동부(5)는 제어부(4)의 제어에 따라 플랩을 개폐한다.The flap drive unit 5 opens and closes the flap under the control of the control unit 4.

보다 구체적으로 설명하면, 제어부(4)는 차속 감지부(1)와 풍향/풍속 감지부(2)로부터 검출된 차량의 속도와 풍향/풍속을 입력받는다. 이는 차체의 프런트에 위치한 플랩이 외부적인 요인에 의해 직접적인 영향을 미치게 되는 인자이다.In more detail, the controller 4 receives the speed and the wind direction / wind speed of the vehicle detected by the vehicle speed detector 1 and the wind direction / wind speed detector 2. This is a factor in which the flap at the front of the body is directly influenced by external factors.

이러한 제어부(4)는 풍향과 풍속에 따른 차속 보정값(VS_CompenWV)을 차량의 속도에 반영한 보정속도(차속+VS_CompenWV)가 플랩 구동용 모터 토크 최대치와 상응되는 속도(VS_SafetyMaxTorque) 이하일 때 플랩 개폐 제어를 수행한다. 차량이 저속 주행일 때는 온도에 따라 플랩 개폐를 제어한다.The controller 4 controls the flap opening and closing when the speed (vehicle speed + VS_CompenWV) reflecting the vehicle speed correction value VS_CompenWV according to the wind direction and wind speed is equal to or lower than the maximum speed (VS_SafetyMaxTorque) corresponding to the maximum motor torque for flap driving. To perform. When the vehicle is traveling at low speed, the flap is opened and closed according to the temperature.

다음으로, 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 방법을 설명하면 다음과 같다. 도 2는 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 방법을 설명하기 위한 순서도이다.Next, an active air flap control method of a vehicle according to an embodiment of the present invention will be described. 2 is a flowchart illustrating a method of controlling an active air flap of a vehicle according to an exemplary embodiment of the present invention.

도 2를 참고하면, 먼저 풍향과 풍속을 입력받아 풍향과 풍속에 따른 차속 보정값(VS_CompenWV)을 연산한다(S1).Referring to FIG. 2, first, the wind direction and the wind speed are input to calculate a vehicle speed correction value VS_CompenWV according to the wind direction and the wind speed (S1).

그리고, 차량의 속도에 차속 보정값(VS_CompenWV)을 반영한 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque)를 초과하는지 비교한다(S2).Then, it is compared whether or not the correction speed (vehicle speed + VS_CompenWV) reflecting the vehicle speed correction value VS_CompenWV exceeds the first reference speed VS_MaxTorque (S2).

여기서, 제1기준속도(VS_MaxTorque)는 무풍속/무풍향 조건시 플랩 구속현상을 발생시키지 않고 개폐 가능한 차속, 즉 플랩 구동용 모터 토크 최대치와 상응하는 속도이다.Here, the first reference speed VS_MaxTorque is a speed that corresponds to a vehicle speed that can be opened and closed without generating flap restraint under no wind speed / no wind direction, that is, a maximum motor torque for flap driving.

이때, 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque) 이하이면 보정속도(차속+VS_CompenWV)가 제2기준속도(VS_SafetyMaxTorque)를 초과하는지 비교한다(S3)At this time, if the correction speed (vehicle speed + VS_CompenWV) is less than or equal to the first reference speed VS_MaxTorque, it is compared whether the correction speed (vehicle speed + VS_CompenWV) exceeds the second reference speed VS_SafetyMaxTorque (S3).

여기서, 제2기준속도(VS_SafetyMaxTorque)는 무풍속/무풍향 조건시 플랩 구속현상을 발생시키지 않고 개폐 가능한 제1기준속도(VS_MaxTorque)에서 안전을 위한 소정 값을 뺀 속도이다.Here, the second reference speed VS_SafetyMaxTorque is a speed obtained by subtracting a predetermined value for safety from the first reference speed VS_MaxTorque that can be opened and closed without generating a flap restraint phenomenon in a windless / no wind direction condition.

보정속도(차속+VS_CompenWV)가 제2기준속도(VS_SafetyMaxTorque)를 초과하면 플랩을 오픈 구동한다(S4).If the correction speed (vehicle speed + VS_CompenWV) exceeds the second reference speed VS_SafetyMaxTorque, the flap is open-driven (S4).

즉, 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque) 이하와 제2기준속도(VS_SafetyMaxTorque) 초과 사이의 범위에 있으면 플랩을 오픈 구동한다.That is, if the correction speed (vehicle speed + VS_CompenWV) is within the range between the first reference speed VS_MaxTorque and the second reference speed VS_SafetyMaxTorque, the flap is open-driven.

이어서, 보정속도(차속+VS_CompenWV)와 제3기준속도(VS_SafetyMaxTorque-HYS)를 비교한다(S5).Next, the correction speed (vehicle speed + VS_CompenWV) and the third reference speed VS_SafetyMaxTorque-HYS are compared (S5).

여기서, 제3기준속도(VS_SafetyMaxTorque-HYS)는 플랩의 빈번한 개폐 방지를 위해 히스테리시스 값(Hystersis value)을 뺀 속도이다.Here, the third reference speed VS_SafetyMaxTorque-HYS is a speed obtained by subtracting a hysteresis value to prevent frequent opening and closing of the flap.

보정속도(차속+VS_CompenWV)가 제3기준속도(VS_SafetyMaxTorque-HYS) 이하이면 플랩을 클로즈 구동한다(S6).If the correction speed (vehicle speed + VS_CompenWV) is less than or equal to the third reference speed VS_SafetyMaxTorque-HYS, the flap is closed (S6).

그리고, 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque)를 초과하면 경고등을 온 한다(S7).When the correction speed (vehicle speed + VS_CompenWV) exceeds the first reference speed VS_MaxTorque, the warning lamp is turned on (S7).

또한, 보정속도(차속+VS_CompenWV)가 제2기준속도(VS_SafetyMaxTorque) 이하와 제3기준속도(VS_SafetyMaxTorque-HYS) 초과 사이의 범위에 있으면 플랩을 온도에 따라 제어한다(S8).In addition, if the correction speed (vehicle speed + VS_CompenWV) is within the range between the second reference speed VS_SafetyMaxTorque and greater than the third reference speed VS_SafetyMaxTorque-HYS, the flap is controlled according to the temperature (S8).

온도에 따른 제어는 냉각수 온도와 오일온도와 모터 온도와 등의 온도가 외기온도에 따라 달라지는 기준온도 초과시 플랩을 개방하고, 기준온도 이하일 때는 플랩을 클로즈 한다.Temperature-based control opens the flap when the temperature of the coolant temperature, oil temperature, motor temperature, etc. exceeds the reference temperature, which depends on the outside temperature, and closes the flap when the temperature is below the reference temperature.

이와 같이, 본 발명은 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 함으로써 고풍속/맞바람의 경우 플랩이 오픈되지 않는 치명적인 오류를 방지할 수 있다.As described above, the present invention enables the flap to be opened and closed within the upper limit of the motor torque in consideration of the speed and wind speed / wind of the vehicle, thereby preventing a fatal error in which the flap does not open in the case of high wind speed / wind.
